2 Agenda System management Operations Manager for z/vm Storage management Backup and Restore Manager for z/vm Tape Manager for z/vm Archive Manager for z/vm Summary 2 IBM z/vm Management Software

3 Automating Operations Operations Manager for z/vm

4 Operations Manager for z/vm Increase productivity Authorized users view and interact with monitored virtual machines without logging onto them Multiple users view/interact with a virtual machine simultaneously Improve system availability Monitor virtual machines and processes Take automated actions based on console messages Reduce problems due to operator error View & interact with consoles View spool files Monitor spool usage Console monitoring Service Virtual Machine being monitored Schedule tasks Operations Manager for z/vm Take action Console monitoring Service Virtual Machine being monitored Automation Routine activities done more effectively with minimal operations staff Schedule tasks to occur on a regular basis Integration Fulfill take action requests from OMEGAMON XE on z/vm and Linux 4 IBM z/vm Management Software

5 Features and Functions Monitor service machine consoles Monitor spool usage Monitor system events View and interact with monitored consoles from authorized user IDs Find and view spool files Schedule events/actions Dynamic configuration Separation of access control 5 IBM z/vm Management Software

6 Operations Manager Existing Service Virtual Machine 1 being monitored Existing Service Virtual Machine 2 being monitored Existing Service Virtual Machine 3 being monitored Existing Service Virtual Machine or remote system Authorized Users View and interact with monitored consoles Find and view spool files Update configuration information z/vm Main Server (OPMGRM1) Captures consoles Evaluates rules Triggers schedules Monitors events and spool usage Executes actions or sends them to action processing servers Action Processing Server (OPMGRSn) 0 to n server instances Processes actions as a result of: Console rule matching Spool monitors Event monitors Schedules 6 IBM z/vm Management Software

7 Summary Use Operations Manager to Automate daily operations Prevent problems rather than react to them Automate reactions to problems when they can t be prevented Improve problem determination procedures Increase programmer and operator productivity 7 IBM z/vm Management Software

8 Managing Backup and Recovery Backup and Restore Manager for z/vm

9 Product Overview Backup Requested by administrators Full or incremental Flexible selection of disks and files to back up Review job before submitting for backup Restore Performed by users for their own data Extending to other users available via exit Performed by administrators for any data Selection of data to restore Full screen interface or commands Catalog housed in Shared File System Integration with Tape Manager for z/vm Optional compression of data during backup Call your own compression algorithm Use IBM provided routine Encryption exits available Call your own routine Use vendor-written routine, such as V/Soft Software s Encrypt/Backup for z/vm 9 IBM z/vm Management Software

10 Backup and Restore Manager Service Machines SFS Server (BKRSVSFS) Catalog Server (BKRCATLG) Creates catalog entries in SFS Provides catalog data when requested Authorized Users Request backups Request restores Find data in the catalog z/vm Main Server (BKRBKUP) Verifies configuration information Processes job templates (review and submit) Assigns backup and restore tasks to workers AUTOLOGs workers as needed Worker (BKRWRKnn) Performs backup and restore tasks Sends catalog data to catalog server Retrieves catalog data from catalog server 10 IBM z/vm Management Software

11 Summary Use Backup and Restore Manager to Perform file-level backups of z/vm data Perform image level backups on non-z/vm guest data Perform disaster recovery backups of entire system Easily find and restore data as needed Manage retention of backup data 11 IBM z/vm Management Software

12 Managing Tapes and Tape Devices Tape Manager for z/vm

13 Product Overview Manage tapes Define tapes in a catalog, including: Free or used Retention/expiration information ATL/VTS or manual mount Data Security Erase Group tapes together into pools Ownership and access control Media type Manage devices Define available devices Dedicated or assignable Group devices together into device pools ATL/VTS or manual mount Any other grouping you choose (read only vs. write, location, etc.) Share devices with other systems Manage mount requests Volume specific and scratch requests Standard Label Non-Label Bypass Label Processing 13 IBM z/vm Management Software

14 Key Benefits Effective management of tapes in ATL or VTS Granular access control Expiration processing Notification for low threshold for tape resources Interacts with devices through DFSMSRMS on z/vm Improved accuracy of manual tape processing Granular access control Automated interface to Operator for manual mounts Internal label verification at attach/give and detach (SL only) Read/Write verification at attach/give Integrated management of z/os and z/vm tapes using DFSMSrmm on z/os Optionally use RMM on z/os as the tape catalog for z/vm and z/os tapes Tapes, access control, and retention managed by the existing RMM catalog Accessible via Tape Manager on z/vm Tapes managed by RMM Devices managed by Tape Manager 14 IBM z/vm Management Software

15 Access Control Authority Sys Admin Modify Pool Attributes and Delete Pool Modify Tape Attributes Add Tapes to the System Inventory (System Free Pool or Private Pools) Delete Tapes from the System Inventory Transfer Tapes into or out of this Pool; Delete External Tapes from this Private Pool Modify Tapes Read Tapes Tape Attributes Modified Only as a Byproduct of Other Commands Use Tape Pool as a Free Pool Receive messages related to this pool Pool Admin Tape Write Read None Free ExceptID Threshold messages MntID1 and MntID2 Mount messages, query and cancel mounts 15 IBM z/vm Management Software

16 Tape Mount Support: ATL, VTS, Manual Verify authorization DFSMSRMS on z/vm Find an available and compatible device Tape Manager for z/vm Internal label verification at attach/give and detach (SL only) Read/Write verification ATL VTS Operator Console on z/vm Manual Mount Drives 16 IBM z/vm Management Software

17 Scratch Mount Requests in Standard Mode Tape Manager Option 1: ATL/VTS Tape Manager finds a specific volser available as scratch in the catalog Manual Tape Manager finds a specific volser available as scratch in the catalog DFSMSRMS Specific volser requested and mounted Operator Console on z/vm: MOUNT VOLSER Operator must mount the specific volser Operator Console on z/vm: Option 2: Tape Manager asks Operator to mount any available scratch tape Option 1 vs. Option 2 controlled by GENSCRATCH statement in SYS CONFIG 17 IBM z/vm Management Software MOUNT SCRATCH Operator can mount any available scratch tape Tape must be in the catalog as scratch Tape must be in requesting mount pool or free pool

18 Data Security Erase (DSE) Erase (sensitive) data before tape is reused Option to enable DSE at tape pool or individual tape level DSE-enabled flag included in each catalog entry DSE-enabled tapes marked as DSE-ready when freed Tape Manager DSE utility (TMDSE) executed on a separate user ID Started manually or automatically with Operations Manager Queries the catalog to find all tapes with DSE-ready flag on Mounts each tape Verifies volume label if possible Configuration option to perform DSE on NL tapes or not Erases tape Turns off DSE-ready flag in catalog Tape is now available for scratch unless its HOLD flag is on 18 IBM z/vm Management Software

19 Tape Manager in Standard Mode Tape Manager Machine (TMTMM) Reads configuration files at startup Interacts with users and applications Device Manager Machine (TMDMM) Library Manager a Machine (TMLM1) Command Manager Machine (TMCMM) Customer defined a (optional) Interacts with real tape devices Attaches/gives drives to end users/applications Verifies volume labels Verifies read/write status Interacts with DFSMSRMS to handle library mounts Handles volume specific and scratch requests One for each RMS server z/vm Supports subcommand processing in user exit Data Security Erase utility ATL synchronization utility Catalog verification utility 19 IBM z/vm Management Software
